We've been raising our two silkies in their brooder since it is too cold for them to go outside, but they are now 2 months old. We bought them diapers so that they could roam around while we're home but we are noticing that one of them never really gets up and supports himself on his legs. He just shuffles backwards without lifting his body. He never has really risin to stretch his legs or walked forward. If anybody has an idea why I would love to know. Thank you.
